San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.
San Diego Rat Control Tip of The Week
Do Rats Pose A Threat To Dogs, Cats, Or Other Pets?
Toxoplasmosis:
There is a parasite that mice and rats can become infected with that causes health conditions in dogs and cats. Toxoplasmosis can cause diarrhea and severe flu in many dogs and it can also change digestive tract functions in cats. This will often be presented as an early infection that leads to a severe flu that can make it difficult for your pet to enjoy a good quality of life. This sickness can also be spread to humans just as easily as it could be spread along to animals.
Roundworms:
Rats often carry roundworms that can be passed on to other animals in your home. There's a variety of medications that can be delivered to treat infections like roundworms. This can also be passed along to humans and if you're experiencing ongoing headaches, digestive issues, fever, or rashes it could be possible that you have been infected.
They Multiply Quickly:
The threat that rats can pose multiplies quickly because they can have an average of 84 babies throughout the course of the year. Working to manage a rat problem can be crucial in the earliest stages before it becomes worse. Without ongoing management of your rat problem, you may end up in a situation where it becomes more difficult to handle the population you are faced with.
Anxiety:
Rats may also cause anxiety in many of your pets. Hearing the ongoing noises in the walls, knowing that they're rather close by and even feeling threatened by rats can be problematic especially for the family pet. Rather than having the ongoing stress that rats can pose for your dog or cat, it may be wise to consider the option of getting a professional exterminator to manage the rat population in your home.
